1Reliability

If optical filters with specific spectral pass-bands and spatial patterns are used to simulate cognitive impairment, then the ability to replicate impaired perception and reaction time is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The optical filter is divided into multiple functional zones with different spectral pass-bands and spatial patterns. Each zone simulates specific aspects of cognitive impairment (e.g., one zone for color perception deficits, another for reaction time simulation), allowing the system to achieve comprehensive simulation effects while managing complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the optical filter are assigned different optical properties (spectral transmission characteristics and spatial patterns) to correspond to different impairment effects. This local differentiation enables the system to replicate specific cognitive impairment characteristics in specific visual fields, improving simulation accuracy without requiring the entire optical system to be overly complex.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

Solution Approach 1:

Multiple optical filter elements with different spectral characteristics are combined into a single integrated goggle system. The filters are arranged to correspond to different visual fields or sequential viewing zones, allowing users to experience the combined effects of multiple substances (e.g., marijuana and alcohol impairment simulation) while maintaining a unified, comfortable wearing experience through a single device rather than multiple separate filters.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The optical goggle system is designed to simulate multiple drug combination effects simultaneously through a single device. The multiple optical filter elements are configured to work together to replicate the cumulative impairment effects of consuming marijuana and alcohol together, providing a universal simulation tool that can model various substance combination scenarios without requiring multiple separate devices.

AI summary

Methods for simulating effects of impairment caused by recreational consumption of marijuana and/or alcohol using a system including optical filters and various radiant objects. The system includes i) an optical filter having a pre-defined spectral pass-band and a non-diffractive spatial pattern configured to deviate a beam of light incident onto the filter, and, optionally, ii) radiant objects at least one of which delivers light in a spectral band corresponding to color that is complementary to the color defined by the pass-band of the optical filter. Method for demonstration and analysis of impairment of cognitive function caused by using the system to affect the vision of the user.
